| Lighthouse will now start to reconstruct the historic states from `slot 10485760`. At this point, if you do not want a full state reconstruction, you may remove the flag `--reconstruct-historic-states`. When the process is completed, you will have the state data from `slot 10485760`. |

So if I'm understanding correctly, the flag --reconstruct-historic-states is only necessary here to "trick" the database into thinking it is going to perform state reconstruction and so doesn't prune states? Otherwise this is just effectively checkpoint syncing to an older state and then syncing forwards as normal (minus state pruning). Does that mean that over time you'd have to repeat these steps to control state db growth?

Yeah, once you sync like this your node keeps all states newer than the checkpoint. In practice it shouldn't be too bad, because state diffs are magic, but I guess users doing this are really interested in saving space. We could add a note along these lines?

If state pruning is already disabled with the flag --reconstruct-historic-states, how to prune states again? Is it done via the manual pruning steps?
So if saving space is a goal, then have to kind of do the manual state pruning from time to time? Because once --reconstruct-historic-state is used, automatic state pruning will not be active for the database from my understanding

Yeah I added some text at the end here which just says to repeat the process
